I just saw on youtube that after the first Lewis fight, Rahman was offered money by HBO for a rematch, and Showtime offered him money for a fight with Mike Tyson. How does the Tyson vs. Rahman fight pan out. I believe the year was 2001, so a prime Rahman vs. a 2001 Tyson.
Tyson gets him early or gets dragged into a long, mauling type fight where he'd look ordinary for most of it. I don't see Rahman landing enough solid blows to knock Tyson out, but he'd score with some decent shots and keep Tyson honest. Tyson would regress a bit the longer the fight lasted and fight in spurts, but may do enough to keep his momentum going and either win on points or score a stoppage late.
